ALFRED H. WORREST, OF LANCASTER, PENNSYLVANIA.

HUB-ATTACHING DEVICE.

To all whom it may concern:

Be it known that I, ALFRED H. WoRREsT, of Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Hub-Attachin Devices; and I do hereby declare the fol owing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in hub-attaching devices,one object of the invention being to provide simple and eflicient means to prevent rocking or rattling of the axle-box.

A further object is to provide means which will operate to compensate for wear.

Afurther object is to so construct a hub-attaching device employing a spring for effecting compensation for wear and for preventing ratt ing and rocking of the axle-box, that maximum life of said spring will be insured.

A further object is to provide, in ahubattaching device, a thrust bearing em loying a spring-pressed member, which shal be so constructed that the spring will not be subjected to excessive strain and vibration.

With these objects in view the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings, Figure 1 is a sectional view, partly in elevation, illustrating my improvements. Fig. 2 illustrates, in front and side elevation, the splitring. Fig. 3 illustrates the convex ring. Fig. 4 illustrates the butt ring, and Fig. 5 shows face and side views of the spring.

1 represents an axle and 2 the spindle at the end thereof,a dust flange or ring 3 being located at the juncture of the spindle with the axle. The major portion of the spindle is made tapering, as is the usual custom, and at the inner end of the tapering portion of the spindle shown in Fig. 1, said spindle is provided with a screwthreaded portion 4 on which a rin 5 having a convex outer face is located,t%is convex ring constituting, in effect, a partly-spherical enlargement on the spindle. Between the threaded portion 4 and the flange 3, the spindle is made cylindrical in form and provided with a groove 6 which communicates with or forms a continuation of the oil Specification of Letters Patent.

groove which extends to the outer end of the spindle.

An axle-box 7 is mounted on the spindle and at its inner end is made with an enlarged portion 8 having a curved forward wall 9 bearing against the convex ring 5. The inner end of the enlarged portion of the axlebox is screwthreaded interiorly for the accommodation of external screwthreads on a butt ring 10. This butt ring is mounted on the cylindrical portion of the spindle and is made with a flange 11 which overhangs the flange 3. By thus forming the butt ring a shoulder 12 is provided against which the inner end of the axle-box abuts, and also provides an internal shoulder 13, between which latter and the flange 3 a packing ring 14 of cork or other suitable material is located. The outer end of the butt ring is made with a convex face 15, against which bears the concaved face 16 of a split ring 17. This split ring is mounted upon the cylindrical portion of the spindle and is provided with a tongue 18 which enters the groove 6 in the spindle. \Vithin the space between the ring 17 and the ring 5 a coiled spring 19 is located and bears at its respective ends against said rings.

From the construction and arrangement of parts above described it will be seen that the spring 19 operates, through the medium of t e s lit ring 17 and butt ring 10, to draw the axle-box 7 inwardly and cause it to maintain a proper bearing against the convex ring 5 and upon the spindle. The butt ring 10 and split ring 17 cooperate to form a thrust-bearing and by making the butt ring with a convex face bearing against the concaved face of the split ring, it is apparent that any strain which would tend to move the axle-box out-' wardly will cause a compression of the split ring 17 and, in consequence thereof, a clamping of said split ring to the spindle. By thus causing the split ring to be automatically clamped to the spindle when the axle-box is subjected to excessive strain endwise, the spring 19 will be relieved of excessive strain or vibration and thus the life of this spring will be prolonged.

My improvements will effectually prevent rocking or rattling of the axle-box by maintaining the same always in proper relation to its bearing on the spindle and will also operate to compensate for wear.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is,

1. The combination with an axle spindle and an axle-box having a bearing on the spindle, of a butt ring secured to the axlebox and provided with a convex forward end, a ring mounted on the spindle and provided with a concave face bearing against the convex end of the butt ring, and a spring bearing against the ring on the spindle.

2. The combination with an axle spindle and an axle-box, of a butt ring secured to the inner end of the axle-box and provided with a convex outer end, a split ring connected with the spindle and provided with a concave face bearing against the outer convex end of the butt ring and a spring bearing against said split ring.

3. The combination with an axle spindle and an axle-box having an enlarged inner end, of a convex ring secured to the spindle and constituting a bearing for the axle-box, a butt ring screwed into the inner end of the axle-box and provided with a convex outer end, a split ring connected with the spindle and provided with a concave face bearing against the convex end of the butt ring and a spring located between the split ring and the convex ring.

4. The cornbinatlon with an axle spindle having a groove therein and an axle-box having an enlarged inner portion, of a convex ring screwed on the spindle and forming a bearing for the axle-box, a butt ring screwed into the inner end of the axle-box and provided with a convex outer end, a split ring on the spindle and provided with a tongue entering the groove in the latter, said split ring having a concave face engaging the convex end of the butt ring, and a spring disposed. between the split ring and the convex ring.

5. The combination with an axle spindle and an axle-box, said spindle having a flange at its inner end, of a butt ring screwed into the inner end of the axle-box and having a flange which overhangs the flange at the inner end of the spindle, said butt ring also having an internal shoulder, packing between said shoulder and the flange on the spindle, and a spring pressed ring located on the spindle and bearing against the outer end of the butt ring.

6. The combination with an axle spindle and an axle-box, of a butt ring secured to the axle-box and provided with abeveled outer end, a split ring connected with the spindle and having a beveled face bearing against the beveled outer end of the butt ring, and a spring bearing against said split ring.

Intestimony whereof, I have signed this specification in the presence of two subscribing witnesses.
